dmraid ignores partitions on primary array

I have two RAID 0 arrays on my installation.  One array is two OCZ SSDs (named Sigma) and the other is a 2TB array (named Chi) for storage  purposes. Both arrays were build using the Intel Matrix Storage Manager tool on my motherboard (just above the BIOS), and partitioned with a live-session of GParted. Originally when I installed Arch, dmraid did not pick up on the partition of the 2TB array, just the drive itself.  I decided to rebuild the 2TB array, and the problem has reversed; dmraid will pick up on the storage partition of the larger array, but ignores the two partitions on the SSD array (it still sees the other array though). This means that I cannot boot into my installation on the SSD array, and have to run a live-session off of a USB drive to troubleshoot. The SSD array has two partitions, one for Windows and another for Arch so I can dual boot for gaming and non-open source software purposes.

I am currently running a live session of Ubuntu, which acknowledges both arrays and all partitions just fine.  All the commands listed below are from the live-install running, but chrooted into my install on the SSD array.

Here is the error I get in grub when trying to boot:

Activating dmraid arrays...
Waiting 10 seconds for device /dev/mapper/isw_cjcefcajfc_Sigmap2
Root device '/dev/mapper/isw_cjcefcajfc_Sigmap2' doesn't exist attempting to create it.
Error: Unable to determine major/minor number of root device '/dev/mapper/isw_cjcefcajfc_Sigmap2'

Here is the output of dmraid -tay on the Arch install (chrooted):

Thanks for taking the time to help me troubleshoot my install, I'm looking forward to getting my desktop to run Arch Linux.
